' fication.

Centrifugal machines and 'in particular tliosein which large quantities.of liquids are to be separated from each other or from more vor lesssolid constituents, necessitate as is Well known a considerable amountof working power. This is due to the fact that a very high speed must beimparted to the masses of liquids which are admitted at a low speed,.since the intended separation canA be effected only at high speed.A Theliquids thus separated possess, however, this high speed still aftertheseparation and in leaving the centrifugal machine the energy whichhas been imparted tothe liquids is thus lost without being utilized.

Now according to the present invention, theenergy impartedl to tlieliquids is co-n vertedr into mechanical work by means of turbine-likedevices. In the simplest man ner this is eiiected in centrifugalmachines which are provided with a rotary casing. A centrifugal machineof this kind is illustrated by way of example in thwaccompanyingdrawing, in which Figure .l is a. vertical section of the upper part ofthe rotary machine casing, and Fig.

2 is' a plan view' partly in.l section on the line A--B.A

The casing a of the machine is rotatably journaled about itslongitudinal axis and being-connected'with the driving Shaft, mayeither'derive its rotary power from the latter or transmit rotation tothe driving shaft. The mode of connecting the casing with the drivingshaft, the separating device located within the casing, theconveyingmechanisni as well as the device for admitting the liquids tobe separated, and those for discharging the more or less solidconstituents, form no partfof the present invention, and have,therefore, been. omitted. Y

Arranged on' the rotary' casingck is av cover b, provided on itscircumference with blades c.- These blades are constructed in exactlythe same manner as turbine blades soV that the `cover b may vbe lookedupon-as a turbine adapted to drive the casing a, provided the pressuremedium is discharged from the casing 4a through the blades.v v In -theevent of several liquids separated in the tentrifugal machine being sodischarged,`

each liquid may be caused to4 first pass Athrough a turbine deviceintended forvdriving purposes.

The shaft of the centrifugal machine may `be horizontal, vertical, ormay have an ob` lique position if desired. By reference, however, it isarranged in a horizontal position. The resent invention may, moreover,be used-in such a manner that not only y the liquid but also the solidconstituents aise caused to pass through the turbine-like arrangementand their energy to be converted into work in theturbine device. Thismode of using lthe invention will be resorted to in all cases wherelarge quantities of solid con- '.stituents are 'obtained and if desiredin connect-ion with the utilization of the energy involved in theoutgoing liquid,` for instance, in the manufacture of sugar. In thiscase the blades will obviously be arrangedv on that end at which thesolid constituents are separated.

Claim: y l

In a centrifugal machine, the combination with a rotaifyr drum, of acover for said drum having inclosed outlets leading there- 'from incommunication with the interior of the drum, .the walls of said outletsbeing curved in a direction opposite to the direction of rotation'. ofsaid drum whereby the energy'spent in imparting motion'to the liquid maybe recovered and assist in roltating the centrifugal machine, the.roofof said outlets being upwardly` andrearwardly curved whereby the liquidmay readily enter and discharge therethrough, and a plate in- .serted atan incline in each of said outlets and adapted to direct the. outgoingliquid against the forward walls of the outlets substantiallytangentially to the rotation of the machine, v
